What is activated aluminum?
Activated Alumina also known as activated, is often referred as “activated” alumina which uses alumina for the catalyst. It is porous and high-dispersion material that has a large amount of surface area. The surface is characterized by the properties required for catalysis such as excellent thermal stability, adsorption, and surface activity. Spherical activated aluminum pressure swing oil adsorbent consists of white, spherical particles. The activated aluminum has uniform particle size. It also has a smooth surface. The activated alumina can effectively dry out trace water. It is suitable for heatless regeneration equipment.
Uses of activated Alumina
The main uses of activated alumina are in water purifiers. The adsorption of gas, water vapour and some liquid humidity is possible with activated alumina. It is possible to revive the adsorption by heating between 175315°C in order to remove any remaining water. You can perform the adsorption process and resurrection multiple times. As well as being used for desiccants, it can absorb vapors from lubricating oil polluted with oxygen, hydrogen or carbon dioxide. It can also serve as a catalyst, catalyst carrier, and a chromatographic analyzer.
It can be used for defluorinating drinking water that contains high levels of fluorine, for defluorinating circulating alkanes to produce alkylbenzene or for deacidification regeneration for transformer oil. Also, it is suitable for gas drying in the electronics, textile and oxygen industries. The dew point of the product can reach as low as -40 degrees Celsius. In the chemical fertilizer industry, the dew point is -40, while in the petrochemical and air separation industries, the dew point is -55. It is an effective desiccant that can be used to dry out trace water. It is a great choice for non-heat regenerative devices.
Activated Alumina is characterized by a large surface area, diverse pore structure and distribution of pore sizes, as well as rich surface properties. It is used in many different applications, including adsorbents.
Alumina used as an adsorbent or catalyst carrier is a specialty chemical. Its high specificity, as well as its many grades and varieties, is due to the fact that different applications have differing requirements in terms of physical structure. Statistically, the amount that alumina is used as carriers and catalysts exceeds the total amount of catalysts used in silica, activated carbon and diatomaceous soil. This illustrates the central role of alumina when it comes to catalysts and carriers.
